upload your ratos.cfg and printer.cfg please
why are you (in your printer.cfg) doing
when this is already defined in your ratos.cfg
do i need to take it out in my config
you should, it isn't doing anything and will just make it more confusing
but if you hotend fan isn't coming on I would look at the wiring and such, the config looks ok to me
if i use the slicer bar in mainsail it works
and make sure you have it wired according to https://os.ratrig.com/docs/toolboards/btt/ebb-42-12#wiring
that should be controlling the part cooling fan, not hotend fan
if i look to ebb-42 wiring it is on PA2. if i look in RatOS.cfg it is fan_toolhead_cooling_pin=PA1,
i have found it, in started the Wizard i change the setting for the fans. thanks
I seem to have exactly the same problem. Can you tell me what exactly you changed to make it work?
